If Cabelas will take them back and refund your money, I would do that. If they aren't lighting up the subjects enough at only 10 feet, then they are useless. Unless you meant to say yards instead of feet. I've had cams that weren't any good past 25 or 30 feet at night, and they were still useful, I just had to be careful in my setups to be sure the deer would be that close.
The best deal on a decent camera I know of right now is the refurbished Moultrie M80 at Rogers Sporting Goods. I got one and it's working great for me. They are only $60.
